    Cellular assembly of hTRmin telomerase. ( A ) U2OS cells were transiently transfected with constructs encoding F-TERT and either hTRmin, hTR, or empty vector (mock). TERT was immunopurified on anti-FLAG agarose from cell extract 48 hr post-transfection. An aliquot of the bound samples were treated with TRIzol to purify RNA, which was analyzed by Northern blot. In parallel, bound samples were tested for telomerase activity by primer extension using 32 P dGTP for radiolabeling. Products were precipitated and resolved by denaturing gel electrophoresis. A radioactive oligonucleotide recovery control (RC) was added prior to precipitation. For the hTR cell extract, different amounts of extract were assayed relative to the hTRmin sample set at 100%. All lanes are from the same gel. ( B ) HCT116 hTR KO#2 cells were transiently transfected to express hTR, CAB-box-mutant hTR (G414C), LhTRmin, or hTRmin. FISH was performed to detect the RNAs (green). Nuclei were counterstained with DAPI (blue). DOI: http://dx.doi.org/10.7554/eLife.18221.004

    Recovery of nucleic acids and polyphosphate (polyP) using various purification methods. Known quantities of bacteriophage lambda DNA (DNA, striped bars), polyG (RNA, white bars), or long-chain polyP (black bars) were processed for nucleic acid purification using Qiaquick, DNeasy, or TRIzol kits, following the manufacturer’s instructions, or with phenol/chloroform extraction. Nucleic acid recovery was quantified using A 260 and polyP recovery by digestion with PPX1 and PiBlue assay. Results are plotted as percent of the input amount in each experiment. For all experiments except the Qiaquick kits, the three samples were: (A) DNA alone (5 µg lambda DNA); (B) RNA alone (5 µg polyG); (C) 5 µg polyP alone; (D) a mixture of 5 µg polyP plus 5 µg of DNA; or (E) 5 µg polyP plus 5 µg of RNA (E) . Experiments with the Qiaquick kit employed 2.5 µg of polyP and/or nucleic acid. Data are mean ± SEM ( n = 3).
